Items become "invisible" - production, walls, animals

[Jekko]

I'm trying a run through with a boat-load of mods. About 20 hrs into this run a glitch started to appear where certain objects are invisible (such as walls made out of specific materials), animals blink in and out of visibility, and production items are visible when built/installed vertically but become invisible when rotated to the horizontal orientation. Is anyone aware of a specific mod that has a history of causing this kind of glitch?

Hi,
nothing heared about something similar to this.
But if you got error's (red text) right after you start Rimworld with all the mods, before you load a safegame, you should investigate into that.
